Roommate search

The search for a motorhome in the Western High Plains of Kansas has just not panned out. Poor planning on my part made it more difficult. I am now looking into trying to secure a room in a home in South Florida for my first assignment and shopping for the motorhome in the spring at the end of my assignment. Has anyone tried this? I foolishly listed (and paid) at one of the roommate search sites but only had one contact. I responded quickly but so far have had no response back. Spoke with a couple realtors who advertized in the local paper (in Florida) as having rooms for rent but they act as agents for others. I suppose I could go with the provided housing but would rather have the subsidy and find my own. Any ideas?

Thanks
